Darwin is not a "god" who is worshipped. The modern theory of evolution is not the same as the theory proposed by Darwin.
Perhaps not by you. I'll just point out that many of your pro-macroevolution compatriots place "Darwin fish" on their cars and t-shirts in a similar fashion to the way Christians iconize the "Jesus fish."
Darwin is a messiah for many.
The modern theory of evolution is not the same as the theory proposed by Darwin.
Mostly because while Darwin was writing, a Bible-believer named Gregor Mendel was doing the hard experimental research that founded an actual scientific discipline - genetics.
While genetics actually explains the transmission of genotypic traits and their phenotypic expression in an objective and verifiable way, it also demonstrates that spontaneous mutations in the genotype are rare, that the redundancy in DNA and RNA exists to minimize and restrain mutation and that mutations are almost exclusively deleterious and are eliminated from a population within a generationn and therefore populations remain quite stable.
Evolutionary theory has to reconcile the hard fact that the theory requires radical mutational changes - and therefore pure Darwinism has had to be abandoned.
New schemata like punctuated equilibrium are needed to try and bridge this aporia.
BTW, RWP, I'm glad to see you've refocused on the matter at hand.
You say now that the definition of species is an approximation, a human category and subject to change.
Fine by me - the evolutionist's definition of what constitutes a species seems to change to support the argument routinely and I can hardly deny that.
My point is that the "Triangle of U" issue in the cabbage genus and its various species demonstrates that an extremely stable genotypic base remains beneath the hybrids and that while cauliflower and broccoli may be bred to produce broccoflower, they cannot be bred to produce broccorabbit or a new species of elm.
No so-called creationist denies the reality of genetic variation - they deny the evolutionist claim that radically different types or kinds are produced spontaneously, in any timeframe, from another kind of creature.
And genetics, as an observed and replicable phenomenon, shows that such radical mutation is counter to the way genotypic transmission actually works.
